Conditions that may trigger the system even if there is no possibility of a collision
■
In any of the following situations where the frontal area of the radar sensor is interrupted,
the radar sensor may detect possibility of a frontal collision and the system may be acti-
vated.
When passing by an oncoming vehicle in a curve or a turn to the right or the left
●
When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
●
etc.)
When there is a structural object (billboard, low ceiling, fluorescent light, etc.) above
●
the uphill road ahead
When driving on a narrow road or through under a low overhead structure (bridge,
●
tunnel, fly-under, etc.)
When driving on an uneven road surface
●
When there is a metal object, bump, or protrusion on the road surface
●
When vehicle' s front part is raised or lowered depending on loading conditions
●
When the direction of radar sensor is misaligned by strong impact applied on an area
●
around the radar sensor, etc.
When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
●
When the front of your vehicle is pointing upwards (caused by putting a heavy load in
●
the luggage compartment etc.)
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retract quickly and the brakes may be applied with a force greater
than normal. When the seat belt is locked in the retracted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
Obstacles not detected
■
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
Situations in which the pre-collision system does not function properly
■
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
●
If a vehicle suddenly moves in front of vehicle, such as at an intersection
●
If a vehicle suddenly cuts in front of vehicle, such as when overtaking
●
In inclement weather such as heavy rain, fog, snow or sand storms
●
When your vehicle is skidding with the VSC system off
●
When an extreme change in vehicle height occurs
●
When the axis of the radar is out of adjustment
●
Due to greatly turning the steering wheel when an obstacle suddenly appears ahead
●
